Police searched the area but could not find the vehicles involved, nor any victims or suspects, Wilson said.

No injuries or other damage was reported.

About half an hour later, a man arrived at Memorial Health University Medical Center with a gunshot wound to his foot.

Detectives interviewed the man. He gave conflicting stories but said he was not involved in the gunfight, police said.

"Instead, he told investigators he had been the victim of an armed robbery in the parking lot of the Family Dollar in Garden City," Wilson said.

Police described the man's medical condition as non-life-threatening.

The gunfire between the two vehicles is under investigation.

Eastside house fire is ruled accidental

An electric sander was the cause of a fire at an east Savannah home, fire officials said Tuesday.

Firefighters were called to a home at 1015 E. 32nd St. shortly before 4 a.m. after receiving a report of heavy smoke in the area, said Savannah Fire and Emergency Services spokesman Capt. Matthew Stanley.

Firefighters forced their way into the home after spotting smoke drifting from the eaves of the two-story house.

"They searched the home and found it was vacant and under renovation," Stanley said.

Investigators indicated the fire was started by an electric sander left plugged in on the second floor, he said.

Firefighters said that while the fire started on the second floor, it spread under the flooring and into the walls.
